Mostly Fake


My limited coronavirus postings, which have nothing to do with coronavirus but everything to do with fake this and fake that:

WHO says fake coronavirus claims causing 'infodemic'
Feb 2020, BBC News

WHO says false information "spreading faster than the virus itself"

I mean, come on, it's immaterial; the noosphere knows not the limits of physical reality let alone biological contagion etc.

Scared and especially sick people are especially vulnerable to misinformation. Desperation will make you believe anything.

What's so bad about fake information?

Sure taking a handful of vitamin C isn't going to kill you, but drinking a glass of bleach might (sorry I drafted this before the thing happened). You never know which miracle cure is coming out of the bag. But what's also detrimental is that fake cures give people a fake sense of security, which is dangerous because when you think you're safe, you behave differently. You go out to the store, you don't wash your hands, you name it. And that makes you more likely to get sick, and more likely the virus will spread to others.

Those who spread misinformation aren't deliberately trying to hurt anyone, not necessarily. In fact, they don't even care about the virus. They just want to divert traffic, they want to snag all the clicks they can, and spinning the most popular thing at the moment is the best way to do that. Donald Trump is President?

Novel Coronavirus (2019-nCoV) Situation Report 13
Feb 2020, WHO

The 2019-nCoV outbreak and response has been accompanied by a massive ‘infodemic’ - an over-abundance of information – some accurate and some not – that makes it hard for people to find trustworthy sources and reliable guidance when they need it.

Organization is working 24 hours a day to identify the most prevalent rumours that can potentially harm the public’s health, such as false prevention measures or cures. These myths are then refuted with evidence-based information. WHO is making public health information and advice on the 2019-nCoV, including myth busters, available on its social media channels and website.

Coronavirus - The seven types of people who start and spread viral misinformation
May 2020, BBC News

Great simple shortlist of the generators of fake news:

  • The Joker - just kidding though
  • The Scammer - everything can be commodified, including your gullability
  • The Politician - also a business relationship
  • Conspiracy Theorist - somewhere between entrepreneur, psychotic, teacher, preacher and scientist
  • The Insider - likely a conspiracy theorist, and lying about their insider status
  • Relatives - alarming things make people worry, and then they tell those they care about, including you
  • Celebrities - they have huge platforms

Coronavirus - Far-right spreads Covid-19 'infodemic' on Facebook

(Coronoavirus) Research links personality traits to toilet paper stockpiling
June 2020, phys.org

The most robust predictor of toilet paper stockpiling was the perceived threat posed by the pandemic; people who felt more threatened tended to stockpile more toilet paper. Partly, this effect was based on the personality factor of emotionality—people who generally tend to worry a lot and feel anxious are more likely to feel threatened and stockpile toilet paper.

The personality domain of conscientiousness—which includes traits of organization, diligence, perfectionism and prudence—was also a predictor of stockpiling (p = .048).

Other observations were that older people stockpiled more toilet paper than younger people and that Americans stockpiled more than Europeans.

The researchers pointed out that the variables studied explained only 12% of the variability in toilet paper stockpiling, which suggests that some psychological explanations and situational factors likely remain unaccounted for.

Mummy returns: Voice of 3,000-year-old Egyptian priest brought to life
Jan 2020, BBC News

3D-printed voice box based on Nesyamun's vocal tract, which was scanned to establish its precise dimensions.

By using the vocal tract with an artificial larynx sound, they synthesised a vowel sound meant to be similar to the voice of Nesyamun.

At least the voice box is now taken care of; maybe we can't upload the whole brain yet, but we're getting there.

I'm the Computer Now


Wave physics as an analog recurrent neural network
Jan 2020, phys.org

This story is the craziest thing I've ever heard -- mind-numbing omnipotent future-speak. Computing with physical wave media in virtual dimensions? I'm in.

The electronic engineering department at Stanford "trained" physical wave systems to "learn" temporal data features.

If you see the word "train" these days you can bet they're talking about deep learning / neural networks. Usually, the way you train a network is to let it watch thousands and thousands of hours of youtube videos. Or any other data set you have available. (The Alcohol Language Corpus of drunk speech, perhaps?)

The network itself learns certain things about all the data you give it, and it assembles itself, arranges itself, to be able to detect those features in other images, let's say. Or you could have it learn what a "Vietnamese sandwich" is, and then synthesize Vietnamese sandwich versions of other sandwiches. Or you could have it show you the eignevector, the essence of a Vietnamese sandwich. (Spoiler, the essence of youtube is the face of a cat. That's what the network learned most by watching a several lifetime's worth of internet-video).

How is eigencat not a thing? Try that search for yourself, "youtube eigencat"

But these guys are talking about teaching not a network, but a wave of air. Not only is it not alive, it's not even a computer! Then again, the waves are the computer:
As proof of principle, they demonstrated an inverse-designed, inhomogeneous medium to perform English vowel classification based on raw audio signals as their waveforms scattered and propagated through it.
-source
You read that correctly. There are no circuits, no electricity. The physical system itself performs a recurrent processing dynamic, based on the way the waves move through space.

It's the new thing, analog machine learning.

Growing crystals to generate random numbers
Feb 2020, phys.org

Generating random numbers has always been a tricky problem for computer engineers because computers were designed to be as predictable as possible. 

One of the more pressing applications of random number generation is data encryption—most existing schemes rely on the constant generation of random numbers. 

The process of crystallization is random due to many factors that come into play as chemicals in a liquid solution evolve from a disordered state to one that is very organized. 

A camera took a picture of each of the cups as crystal formation began. Each of the pictures was converted to a zero or a one based on nothing but the geography of the crystal. The zeros and ones were then strung together to form a random number.

New study allows brain and artificial neurons to link up over the web
Mar 2020, phys.org

Novel Nanoelectronics has enabled brain neurons and artificial neurons to communicate with each other using brain-computer interfaces, artificial neural networks and advanced memory technologies (also known as memristors).

Cultivated lab rat neurons from Padova were distributed into memristive synapses in Southampton, and then connected to artificial silicon neurons in Zurich.

Advanced 'super-planckian' material exhibits LED-like light when heated
Mar 2020, phys.org

"We believe the light is coming from within the crystal, but there are so many planes within the structure, so many surfaces acting as oscillators, so much excitation, that it behaves almost like an artificial laser material," Lin said. "It's just not a conventional surface."

Algorithm quickly simulates a roll of loaded dice
May 2020, phys.org

Random number generation:
The algorithm, called the Fast Loaded Dice Roller (FLDR), was created by MIT graduate students and research scientists. 
FLDR can use up to 10,000 times less memory storage space than the Knuth-Yao approach, while taking no more than 1.5 times longer per operation.

I'm not even sure I understand any of this. This is without a doubt a discussion that would have been impossible to imagine twenty years ago. (Although I think the idea is that "homeless people are free.")
"Should tech companies pay more for dark-skinned subjects because they’re underrepresented in training data? If our bodies are commodities, what’s a fair price, and who should set it? The data-ownership idea is, fundamentally, limited: Even if we manage, with the help of Hughes or Yang or state legislatures, to negotiate a high price for our data, we’re still for sale.

Artificial Memetics


When I search the term "artificial memetics" in 2020, all I get are people talking trash, like liberal artificial memetics, or the artificial memetics of masculinity.

What I'm looking for are robots that make their own memes. What I'm looking for are an army of artificial people to make an entire artificial culture so that we can finally live in a full-service anthroposphere.
